This Holosun 2 MOA red dot is comes with a 1/3 Co-witness mount and is powered by both solar or a CR2032 battery.

Dual reticle means you can choose between just a 2 MOA dot by itself, or an EOTech style 65MOA circle with a 2 MOA dot in the center.

PARALOW HS503CU is a compact red dot sight with the option of a 2MOA dot only or a 2 MOA dot with a 65MOA circle reticle pattern. Employing new LED technology, the life time for one CR2032 battery can reach 2 years if left on constantly. However, the solar technology and automatic brightness features work together to extend the battery life dramatically beyond that for the average shooter. The sight may be installed on various firearms such as shotguns, pistols, rifles, air rifles and crossbows .
